VALVE.

Specification of Letters Patent.

Patented Jan. 26, 1909.

Application led November 9, 1907. Serial No. 401,514.

To all whom it may concern.'

Be it known that I, JOHN M. BEGGS, a citizen of the United States, resident of Grafton, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Valves; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to an improvement in valves and is most advantageously applicable to valves located in the floors of dwellings or similar places for the purpose of controlling the supply of gas to burners. And it is particularly useful where it is desired that the valve shall not protrude above the iioor but shall be iush therewith.

In the construction of valves at present in vogue and where the top does not extend above the floor, it is extremely dii'licult to separate the bonnet from the valve when necessary to do so, for instance, for the purpose of renewing the packing, and the accomplishment frequently entails the removal of and consequent injury to a portion of the floor on account of the di'liiculty of applying a tool to the bonnet to remove it, by reason of its close proximity with the fioor. And when the bonnet is removed the close confines of the neck of the valve makes it difficult to competently do such work as packing.

The object of my invention is to provide such a construction of valve that the parts thereof are adapted to be easily separated 3 and a more accessible neck for the convenience of packing the valve while it is in position. And, a further object of my invention is to construct such a valve that is readily adjustable to the usual difference in the thickness of floors.

In the drawings, Figure 1 is a sectional elevation showing a valve embodying a construction of my invention. Fig. 2` is a section on line 2-2 of Fig. 1 looking in the direction of the arrow. Fig. 3 is a plan view. Fig. el is a view in sectional elevation without the valve body or casing. Fig. 5 is a sectional elevation showing a modification.

Similar reference numerals in the following specification refer to similar parts in the accompanying drawings in which- 6 represents a globe valve in tl e floor 7, and having a bulge or swell portion 8 and a projecting open neck 9 which is tapped at 10. A bonnet 11 has a flange 11 integral therewith and a thread on its outer face adapted to engage the tapped thread 10, and the lower portion of said bonnet is tapped at 12 for engagement with a suitable thread on the valve stem 13 which may thereby be fitted centrally in the opening 14; of the bonnet 11. On the shoulder 15 of the bonnet and around the valve stem is a ring of packing 16 which is properly compressed and retained in position by the bushing 17 which is threaded at 18 to engage a corresponding thread in the bonnet in which it is screwed down to the position shown in Fig. 1. In Fig. 5 an additional bushing 1Q is shown fitted within the bushing 17 and in which it is adapted to be raised and lowered by means of a suitable thread on the bushing 19 engaging a tap 2O in the bushing 17, and allowing the bushing 17 to be raised thereon and adapted to suit the usual variations in the thickness of oors and held in its adjusted position by the screw r.

21. On the wall of the bonnet are recesses 22, and on wall of the bushing 17 are similar recesses 23 (Fig. 5) which are for the purpose of engaging any suitable tool or instrument and facilitating the removal of those parts from the valve.

It will be apparent to those familiar with the art to which this invention concerns that various changes or modifications may be made in the construction herein shown without departing from the spirit of the invention.

lhat I claim as my invention and desire to secure by Letters Patent is:

1. In a valve, a detachable bonnet having a flanged upper portion adapted to engage the top of a valve casing, a countersunk shoulder formed in the bonnet below the fiange, a bushing within the bonnet and adapted to receive a valve key, and means below the countersunk shoulder to carry a valve stem.

2. In a valve, a detachable bonnet having a hanged upper portion adapted to engage the top of a valve casing, a countersunk shoulder formed integral in the bonnet below the flange, a bushing within the bonnet7 and a Ashank below the countersunk shoulder and integral therewith and adapted to carry a valve stem within said bonnet.

3. In a valve, a detachable bonnet having a fianged upper portion adapted to engage the top of a valve casing, a countersunk shoulder formed in the bonnet below the flange, packing arranged on the countersunk shoulder, a bushing adapted to bind thev packing on the countersunk shoulder, a telescoping bushing within said bonnet and adapted to be adjustedto a iioor line, and means on the bonnet to carry a valve stem. l 4. A Valve cmprising a casing, a detachable bonnet having a flanged upper ortion adapted to engage the top of the va ve casing, a countersunk shoulder formed in the bonnet below the flange, packing arranged on the countersunk shoulder, a bushing arranged between said flange and thepacking to bind the packing in the bonnet, a threaded portion connected to the bonnet below the countersunk shoulder, and a valve stem car- 15 red by said threaded portion.

In testimony whereof, I the said JOHN M. BEGGS have hereunto set my hand.
